Enough About Data Breaches. Let’s Talk About OT Security – TAG Cyber

Tag Cyber moderated a roundtable discussion with Mark Weatherford and me on control system cybersecurity.  The discussion was why operational technology (OT) is woefully neglected—and what can be done to change that. This discussion becomes even more timely with the recent DOE 100-Day Plan to Address Cybersecurity Risks to the US Electric System. The roundtable […]

Lack of security at Level 0/1: problem of awareness or unwillingness to change priorities?

To be honest I was planning to write about unintentional cyber incidents in critical infrastructure and the need to pull away some of our attention from the sexy topic of cyber-attacks and cyber kill-chains.  I changed my mind when I read Dale Peterson’s informative article on “Awareness Of Purdue Level 0 and 1 (In)Security” and […]

Observations from 2021 SANS ICS Cyber Security Conference

The 2021 SANS ICS Cyber Security Conference was held March 4-5, 2021 with almost 9,000 registrants globally. The Conference thoroughly addressed OT networking issues. However, cyber security issues associated with Level 0,1 devices were not as adequately understood and addressed. There was also almost no discussion of the hardware backdoors in the Chinese-made transformers. My […]

Texas power outages demonstrate grid cyber vulnerability and inadequacy of existing regulations

Recent Texas power outages and the loss of both electricity and water across Texas demonstrate how vulnerable ERCOT and Texas are to not only natural disasters such as snowstorms and hurricanes but also manmade and malicious activities. More than that, it also demonstrates the vulnerability of the entire U.S. Energy grid. The good news is […]

Don’t overlook the most consequential control system cyber events of 2020

URL: https://www.controlglobal.com/blogs/unfettered/dont-overlook-the-most-consequential-control-system-cyber-events-of-2020/ Two of the most consequential control system cyber events (attacks) in 2020 were supply chain attacks. The first event was the Chinese installing hardware backdoors in large electric transformers, an incident that prompted Presidential Executive Order (EO) 13920. The hardware backdoors are obvious control system threats. The second event was the Russian SolarWinds […]

What would Sun Tzu and Louis Pasteur say about today’s industrial cybersecurity?

Have been following the discussions on industrial cybersecurity, convergence, network vs device security, and IT vs OT vs ICS[2]. Some of the points of view differ greatly on what needs to be done.  This lack of consensus indicates that something may be wrong with our assumptions and our approach.   A disturbing lack progress being […]

A critical look at the CSIS Report “Dismissing Cyber Catastrophe”

Jim Lewis is a Sr VP at the Center for Strategic and International Studies (CSIS). He wrote the article “Dismissing Cyber Catastrophe” dated August 17, 2020 – https://www.csis.org/analysis/dismissing-cyber-catastrophe?utm_source=CSIS+All&utm_campaign=e4d5b3e04c-EMAIL_CAMPAIGN_2018_11_08_05_05_COPY_01&utm_medium=email&utm_term=0_f326fc46b6-e4d5b3e04c-221758737 . In ‘Dismissing Cyber Catastrophe,’ Jim argues that concerns about industrial cyber security are overblown and the risk is exaggerated. Because the view that ‘cyber catastrophes’ are […]
